THE SOLAR WIND HAS ARRIVED: Earth is inside a stream of solar wind flowing from a loosely organized cluster of holes in the sun's atmosphere. Geomagnetic storms are not expected at this time. However, lesser geomagnetic unrest and bright auroras are possible inside the Arctic Circle.

All of these sunspots have simple, stable magnetic fields that pose no threat for strong flares. This situation could soon change, however, because AR2956, 57 and 58 are growing rapidly. Credit: SDO/HMI
